Start transaction

You can process payments using:

• Card reader (recommended)
• Manual card entry

Card reader transaction

let saleEntity = SaleEntity(amount: 22.0, tipAmount: 5)
ClearentWrapper.shared.startTransaction(
    with: saleEntity,
    isManualTransaction: false
) { error in
    // Handle completion
}

Runtime callbacks

During the transaction, the SDK provides updates through delegate methods:

func userActionNeeded(action: UserAction) {
    // Prompt user (for example, insert or swipe card)
}
func didReceiveInfo(info: UserInfo) {
    // Display status (for example, processing)
}

Transaction result

func didFinishTransaction(
    response: TransactionResponse?,
    error: ClearentError?
) {
    if error == nil {
        // Transaction succeeded
    } else {
        // Handle error
    }
}

Manual card entry

Use manual entry when a reader is unavailable.

let saleEntity = SaleEntity(
    amount: 22.0,
    tipAmount: 5,
    card: "4111111111111111",
    csc: "999",
    expirationDateMMYY: "11/28"
)
ClearentWrapper.shared.startTransaction(
    with: saleEntity,
    manualEntryCardInfo: true
) { error in
    // Handle completion
}
